Data Modeling Module Assessment


I am really confused about the instructions for step #2 in this assessment. It says:

Add a new Promoting Events field to the Community Story type that only allows a user to select from Events in the Knowledge Graph.

Am I supposed to be adding a custom field? If so, are there any specific instructions for that?

If the field isn’t supposed to be custom then I cannot find it in the selection. I have tried searching for it and looking for it through every type but I do not see it on my end.
